John Tyler (1790-1862) served as America’s 10th president from 1841 to 1845. He assumed office after the death of President William Henry Harrison (1773-1841), who passed away from pneumonia after just a month in the White House. Nicknamed “His Accidency,” Tyler was the first vice president to become chief executive due to the death of his predecessor. A Virginian, he was elected to the state legislature at age 21 and went on to serve in the U.S. Congress and as governor of Virginia. A strong supporter of states’ rights, Tyler was a Democratic-Republican; however, in 1840 he ran for the vice presidency on the Whig ticket. As president, Tyler clashed with the Whigs, who later tried, unsuccessfully, to impeach him. Among his administration’s accomplishments was the 1845 annexation of Texas. Before he died, Tyler voted for Virginia’s secession from the Union and was elected to the Confederate Congress.
